EI-DVI Deluxe 1912 Single Basket Microprocessor Dissolution Test Apparatus
Product Overview
The EI-DVI Deluxe 1912 Microprocessor Dissolution Test Apparatus is a reliable, solid-state instrument engineered for the essential determination of active drug ingredients in pharmaceutical formulations, specifically tablets or capsules. This device evaluates adequate bio-availability and provides crucial information necessary for formulating therapeutically optimum dosage forms. The 1912 model is manufactured and designed for use in quality control (QC) laboratories and research and development (R&D) settings within the pharmaceutical industry.
Advanced Microprocessor Control and Compliance
This dissolution tester utilizes the latest microprocessor technology and advanced engineering techniques to deliver enhanced accuracy and reproducibility. It is specifically designed to determine compliance with dissolution requirements as per both USP (United States Pharmacopeia) and IP (Indian Pharmacopoeia) specifications. The user interface features friendly prompts throughout the measurement process.
The system is equipped with robust data management facilities, including storage for 200 analyzed samples (automatically stored with batch and sample numbers) and a facility for setting up 20 different test methods in both Routine and Sustain programming modes. These critical test setups are retained in the memory even if the power is switched off. The unit includes provision for attaching a dot-matrix printer via a centronics interface, allowing for the easy printing of stored setups or results.
Design and Operation
The model 1912 is characterized as a single-basket dissolution apparatus, which typically corresponds to the USP Apparatus 1 (Rotating Basket) methodology. This technique is often preferred for evaluating solid oral dosage forms, particularly capsules and certain formulations (like sticky tablets or floating drug delivery systems) that might otherwise adhere to the vessel walls.
The single testing unit includes one unbreakable dissolution vessel of 1000 ml capacity, housed within a sturdy, acrylic water bath. Uniform heating is ensured by a large spread-out stainless steel heater. The stirrer unit is strategically attached by a single column at the back of the instrument to improve accessibility for sampling during the dissolution test.
Precision Stirring and Temperature Management
The dissolution test requires maintaining constant and uniform conditions. The instrument provides programmable stirrer control, with speed accurately regulated and maintained by a microcontroller. It features a dual-channel temperature system, utilizing PT100/Semiconductor sensors, to simultaneously monitor the temperature of the water bath and the dissolution vessel, ensuring stable operating conditions within the specified range. The system provides audio visual indicators for status reporting.
